11 // For the final which is due next week...
12 // Use the 4 voice synthesizer to generated a wave form.
13 // Play the waveform through the speakers.
14 // Plot the waveform using the oscopePanel.
15 // Show a panel with the Power Spectrial Density of the waveform.
16 // Come to class.
17 // Set up your final.
18 // Demo to the class.
19 // Hand in the printout, with floppy.
20 // Go home!
21 // Just like what I did just now, but use 4 voices. Each
22 // is controlled with 7 sliders. You add the output of the 4
23 // voices togther.
